Detailed Description

This class defines special log4cxx appender which "appends" log messages to Python logging. To use this logger one has to explicitly add it to log4cxx configuration using PyLogAppender as appender class name, for example:

log4j.rootLogger = INFO, PyLog
log4j.appender.PyLog = PyLogAppender
log4j.appender.PyLog.layout = org.apache.log4j.PatternLayout
log4j.appender.PyLog.layout.ConversionPattern = %m (%X{LABEL})

Member Function Documentation

append()

void lsst::log::detail::PyLogAppender::append ( const spi::LoggingEventPtr & event, log4cxx::helpers::Pool & p )

override

Forward the event to Python logging.

close()

void lsst::log::detail::PyLogAppender::close ( )

override

Close this appender instance, this is no-op.

requiresLayout()

bool lsst::log::detail::PyLogAppender::requiresLayout ( ) const

override

Returns true if appender "requires" layout to be defined for it.

This appender returns false, we use layout but construct it differently.

setOption()

void lsst::log::detail::PyLogAppender::setOption ( const LogString & option, const LogString & value )

override

Handle configuration options.
